My new smart phone writes good.

As per billy's suggestion, I conducted some Swype Keyboard Dragon Speech Recognition expletive tests.

The results:
Warning, clicking the button below will expose you to doubleplusungood words.

Test sentence number one:
"You fucking dickhead, you prick asshole shit bastard."
Results:
"You fucking dickhead, you prick asshole shit bastard."

Perfect.


Test sentence number two:
"Up your fucking cunt you bitch, you shitty little twat."
Results:
"Up your fucking cunt you bitch, you shitty little Twatt."

Excellent, but not perfect. It records a capitalized "Twatt"
instead of "twat". According to Google: "Twatt" is either  
"A settlement in the Shetland Islands of Scotland."
or
"A settlement in the Orkney Islands of Scotland."

Scotland, it seems, has two Twatts.
